Pi 11- y Patented Dec. 31, 1935 5 Claims.

The invention relates to gas burners and particularly to gas burn rs foruse in connection with boilers used in the oil fields, and has for itsobject to provide a burner comprising an intake pipe terminating in aplurality of spaced feed lines having a plurality of upwardly extendingburner elements mounted thereon and through which gas passes to thecombustion point.

A further object is to provide a gas burner comprising a chamberedcasing having an air mixing chamber therein and mounted on a feed linehaving a discharge pipe discharging upwardly through the mixing chambertowards the burner and air admission holes in opposite sides or" thecasing and through which air is sucked by the upwardly projected gasfrom the feed pipe.

A further object is to provide the feed line casing with an upwardlyextending pipe into which the gas is projected and mixed with the airand a transversely disposed passage at the upper end of the upwardlyextending pipe and discharging into an ovate chamber in an ovate shapedmember above the transverse pipe to the point of combustion above theburner.

A further object is to provide a gas burner comprising an upwardlyextending supply pipe terminating in a transverse pipe, an ovatechambered member connectedto the ends of the transverse member andhaving an ovate chamber, into which gas is discharged and means wherebythe gases from the ovate gas chamber will be discharged upwardly againstthe upper sides of the upwardly and outwardly inclined deflecting platesat a right angle to the transverse pipe. Also to provide an air passageupwardly from opposite sides or" the transverse pipe through the ovateburner and between the deflecting plates.

A further object is to provide an ovate shaped chambered gas burner,into the chamber of which mixed gas and air is discharged, and throughthe center of which air is sucked upwardly by the gases dischargedupwardly from the ovate gas chamber impinging and deflecting outwardlyincident to engagement with the under sides of upwardly divergingdeflecting plates which cause vacuum pockets on the upper sides of thedeflecting plates thereby causing air induction and. entrainment, to thepoint of combustion.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a perspective view of the burner unit.

Figure 2 is a vertical transverse sectional View through the burnertaken on line 2--2 of Figure 1.

Figure 3 is a vertical longitudinal sectional view through one of theburners and a portion or" one of the feed lines.

Figure 4 is a top plan view of one of the burners. 7

Referring to the drawing, the numeral l designates the intake pipe whichterminates in branch pipes 2 at a right angle thereto and connected tothe branch pipes are feed pipes 3 which may be or" any number desired,three being shown for purposes of illustration. Mounted on the feedpipes 3 and extending upwardly therefrom are gas burners 4, all of whichare similarly-constructed and one of which will be described in detail,it being understood that the reference numerals will apply to all theburners. Each burner comprises an upwardly extending casing 5 having achamber 8 therein, which arches the upper side of the feed pipe 3, asclearly shown in Figure 2 and houses the gas port i in the feed pipe.Opposite sides of the casing 5 may be secured at 8 to the feed pipe inany suitable manner, for instance by abrasion, and it will be noted thatthe opposite sides 9 of the casing are provided with air supply portstil, through which air is sucked by the upwardly rushing gas projectedupwardly from the port 1. Air ports I3 are preferably disposed below thedischarge end of the gas port l to insure a suction of air into thechamber 6.

Telescopicallyengaging in the upper end of the casing 5, at l I is anupwardly extending pipe 12, the lower end of which is provided with alug l3 which is received in a recess M in the upper end of the casing 5,and which prevents rotation of the burner supported on the casing andmaintains the same in proper position. The upwardly extending pipe 52terminates'in a transverse portion l5 having a gas passage l6 therein,through which the previously mixed air and gas passes to thesubstantially oval shaped horizontally disposed chamber l! in the burnerproper, and which chamber is in a similarly shaped burner casing I8,which has its upper side open as at I9 at opposite sides of the burnercasing and at a right angle to the transverse portion l5. Burner casingI8 is provided with a centrally disposed air passage 20 through whichair passes upwardly through the burner casing, and through the airpassages 2| at opposite sides of the transverse portion l5, therefore itwill be seen that air will be sucked upwardly by the flame above theburner through the passage 2| to the point of combustion. As the gaspasses upwardly through the chamber I? it engages the under sides 22 ofthe upwardly and outwardly inclined deflecting plates 23 above theburner, and this deflected gas causes a vacuum above the plates 23,thereby causing a suction of the air through the passage 2! to the pointof combustion. It will be noted that the deflecting plates extendupwardly and outwardly from opposite sides of the air passage 20 andthat they extend across the ends of the gas chamber l1, therefore allgas leaving the chamber I! will impinge against the under sides of theupwardly and outwardly inclined deflecting plates, hence gas will notescape around the ends of the deflecting plates.

From the above it will be seen that a gas burner is provided wherein airis admitted and mixed with the gas at two points before it reaches thepoint of combustion, thereby thoroughly merging the same and allowing aproper mixture of air and gas, as the gas expands in the pipe l2 and thechamber 6. It will also be seen that the burner chamber I! dischargesthe gas upwardly in a form other than round against the under side ofthe deflecting plates 23 and in a manner whereby the flame will bespread over a large area and at the same time a vacuum is formed abovethe plates which will induct the air'from the air passage 2! to thepoint of combustion.

The invention having been set forth what is claimed as new and usefulis:

1. A burner assembly comprising an intake pipe, a plurality of feedpipes connected to the intake pipe, a plurality of upwardly extendingburners carried by said feed pipes, said burners each comprising achambered casing mounted on the feed pipe in engagement therewith andhaving air intake ports at opposite sides of the feed pipe, an upwardlyextending pipe carried by the casing in the vertical plane of the feedpipe and into which gas from the feed pipe and air from the chamberedcasing pass, said pipe terminating in an approximately annular chamberedburner casing into the chamber of which the gas and air are discharged,an air passage through said burner casing, discharge means at oppositesides of the upper end of the burner casing and upwardly and outwardlyinclined deflecting plates against the under sides of which gas isprojected, whereby air passing through the burner between the plateswill be inducted to the. gas at the point of combustion.

2. A burner comprising a supply pipe having an upwardly extendingdischarge port, a chambered casing engaging the supply pipe and havingits chamber arching the supply pipe transversely and the discharge porttherein, means for admitting air to the chamber of the casing, anupwardly extending pipe carried by the casing, a transverse 5 pipecarried by the upper end ofthe upwardly extending pipe, a continuouslychambered burner casing carried on the ends of the transverse pipe andhaving a chamber therein in communication with the chamber in thetransverse pipe and the 10 opposite sides of its chamber dischargingupwardly to the atmosphere at opposite sides of the burner casing, saidburner casing having an air passage therethrough with its lower end incommunication with the atmosphere at opposite sides of the transversepipe, the opposite sides of the air passage through the burner casingterminating in upwardly and outwardly inclined deflecting platesextending above the upper discharge ends of the chamber in the burnercasing at opposite g0 sides and across the ends of the chamber in theburner casing.

3. A gas burner comprising a T-shaped gas supply pipe, a continuousburner casing connected to the arms of the T-shaped supply pipe andhaving communication with the chamber of said arms and open to theatmosphere at the upper end thereof, an air port extending through saidburner casing and having communication with the atmosphere at oppositesides of the arms of the T-shaped member and the atmosphere above theburner, and upwardly and outwardly inclined deflecting plates carried bythe burner casing above the discharge end of the chamber therein and inspaced relation thereto, said deflecting plates extending across theends of the chamber in the burner casing. l
